(Updates with comments from TransCanada, details about
allegations and background)

By Mike De Souza

CALGARY Oct 30 (Reuters) - Canada's energy regulator in a
report released on Friday found that six of 16 pipeline safety
allegations against TransCanada Corp were "partially
substantiated."

The National Energy Board (NEB) said it found no reason to
issue any enforcement action in response to the complaints that
were raised by a whistleblower.

The regulator also said it concluded that none of the
allegations posed an immediate threat to the safety of workers,
the public or the environment.

TransCanada, the country's second largest pipeline operator,
said in a statement on Friday that it cooperated fully with the
investigation and that only four allegations involved an
infraction of internal company procedures.

The NEB rejected the most serious allegations of dangerous
welds and the alleged failure to report some incidents to the
regulator. It said these allegations were not substantiated
based on its review of the evidence.

The regulator partially confirmed allegations related to
some minor pipeline damage, inadequate welding work and
inspections, as well as allegations of poor worker safety
practices.

In one case, the company said a welding inspector made an
"honest mistake" by mixing up machines needed to complete a
test.
